Fun Facts

  • 🌱 Bluechip was introduced by Iseli Nursery in Oregon and is a trademarked cultivar selection, meaning it is a specifically chosen variant with consistent characteristics that differ from the species Juniperus horizontalis.
  • 🌱 The silvery-blue color comes from a waxy coating on the foliage called a 'glaucous bloom' that reflects light and provides UV protection while giving the plant its distinctive appearance.
  • 🌱 Junipers, including Bluechip, have been cultivated and valued for thousands of years; juniper wood is highly aromatic and has been used for incense, woodworking, and traditional medicine across many cultures.
